The wastes that may be generated during the production of ammonium metatungstate mainly include the following aspects:
- Wastewater
Production wastewater: A large amount of wastewater is generated during the production of ammonium metatungstate. These wastewaters may come from different production stages, such as tungsten ore extraction, tungsten nitrate precipitation, ammonia addition, etc. These wastewaters often contain harmful substances such as heavy metal ions (such as lead, nickel, cadmium, etc.), ammonia nitrogen, sulfate, etc. If they are discharged directly without treatment, they will cause serious pollution to the environment.
Extraction method APT production wastewater: Taking the extraction method to produce ammonium tungstate (APT) as an example, each ton of APT produced usually produces about 25 to 30 tons of wastewater. These wastewaters are weakly acidic and contain a variety of heavy metal ions and high salinity.
- Waste gas
Process waste gas: Some waste gas may be generated during the production process. These waste gases may contain harmful gases such as ammonia, sulfur dioxide, nitrogen oxides, etc., which need to be treated before they can be discharged.
- Solid waste
Waste residue: In the process of tungsten ore extraction and tungsten nitrate precipitation, some waste residues will be produced. These waste residues may contain valuable elements such as tungsten, sulfur, and arsenic, but may also contain some harmful elements and need to be properly handled.
Waste catalysts and adsorbents: In the process of ion exchange and catalytic reaction, catalysts and adsorbents may be used. These materials may lose activity or saturation after use and become solid waste.
Other solid wastes: such as packaging materials, cleaning materials, etc. Although these wastes do not contain harmful substances, they also need to be properly handled to avoid pollution to the environment.
- Waste liquid
Ion exchange liquid: In the process of ion exchange, waste liquid containing a certain amount of metal ions will be produced. These waste liquids need to be properly handled to avoid pollution to the environment.
In summary, the wastes generated in the production process of ammonium metatungstate mainly include wastewater, waste gas, solid waste and waste liquid. These wastes contain a variety of harmful substances and need to be effectively treated and disposed of to reduce pollution and harm to the environment.
